The announcement, "we recommend you use the mask in the kit that will be distributed after takeoff."
By the time I boarded 30minutes before departure, went for deicing, sat in the line for take off, waited for the seatbelt sign to be turned off,
I had been in the tube for two hours waiting for the recommended mask.

I would suggest distributing something that is allegedly life saving a bit faster. Maybe during boarding.
Like last year.
